Episode 89 of Software Testing with Fexingo: QA, Automation, and Reliable Software Engineering. Lucas and Luna dive into test flakiness as a leading indicator of CI pipeline health. They examine a real-world case from a mid-size e-commerce company where a 3% flaky-test rate masked a deeper infrastructure issue costing the team 40 minutes per developer per day. Lucas explains why tracking flaky test counts alone is misleading and introduces the 'flaky test weight' metric — measuring failures per execution and rerun cost. Luna shares how her team at a fintech startup reduced flakiness by 70% using test splitting and deterministic seed values. They discuss how to set service-level objectives for flakiness, automate quarantine, and avoid the trap of simply re-running tests until green. If you've ever ignored a 'rare failure' in a CI build, this episode will change how you read your test dashboard. #TestFlakiness #CIPipeline #ContinuousIntegration #TestAutomation #SoftwareTesting #FlakyTests #DevOps #QAMetrics #TestReliability #FlakyTestWeight #TestQuarantine #ServiceLevelObjectives #DeterministicTesting #TestInfrastructure #DeveloperProductivity #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
